  • Process for preparing porous material having interconnected pores
    Publication number: 20040099979
    Abstract: The present invention provides a process for preparing a porous material having interconnected pores. One or more kinds of bioresorbable polymers and a low molecular weight oligomer are dissolved in an organic solvent to form a bioresorbable polymer solution. The bioresorbable polymer solution is then exposed to a coagulant to form a porous material. The low molecular weight oligomer is soluble in the coagulant, and the bioresorbable polymer is insoluble in the coagulant.

  • Multi-channel bioresorbable nerve regeneration conduit and process for preparing the same
    Publication number: 20030176876
    Abstract: A multi-channel bioresorbable nerve regeneration conduit and a process for preparing the conduit. The multi-channel bioresorbable nerve regeneration conduit includes a hollow round tube of a porous bioresorbable polymer and a multi-channel filler in the round tube. The multi-channel filler is a porous bioresorbable polymer film with an uneven surface and is single layer, multiple layer, in a folded form, or wound into a spiral shape.

  • Process for preparing porous bioresorbable material having interconnected pores
    Publication number: 20030146532
    Abstract: The present invention provides a process for preparing a porous bioresorbable material having interconnected pores. A bioresorbable polymer and a low molecular weight oligomer are dissolved in an organic solvent to form a bioresorbable polymer solution. The bioresorbable polymer has a molecular weight greater than 20,000 and the oligomer has a molecular weight of 200 to 4000. The bioresorbable polymer solution is then contacted with a coagulant to form a porous bioresorbable material.
